il,23,d l. Specification Application filed May 3916- To aZZ whom it may concern Be' it known that I, ALBERT J. HORTON, a citizen of the United States, residing at "White Plains, in the county of Westchester and State of New York, have invented new and useful improvements in Resistances, of

which the following is a full, clear, concise, Th

and exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to resistances and more particularly to those ofthe unit type.

The invention has among its objects to provide a simple, rugged and compact resistance' device suitable for- 'phonographs and'othermechanisms. 3

Further objects are to provide a resistance unit with simplified terminal and supporting means and to provide for inclosure of :a' number of units in a compact and readily assembled structure.

Other objects will appear as the description proceeds.

In the drawing, wherein is illustrated an embodiment .of the said invention,

Figure l is a top plan viewof a resistance device constructed in accordance therewith;

Fig. 2 is an edge view, partly in section, ofthe resistance device illustrated in Fig. 1, while Fig. .3 is an end view, partly in. section,

Referring to Fig. 1, a plurality ofresistance units 1 (in the present case 3) are tersupported in parallel relation upon a flat base 2, said units being inclosed within a casing 3. a

Referring more particularly to Figs. 2

and-3, each of the aforesaid units comprises lindrical base 5 ofporcelain or other nonconductive material, the respective ends of said resistance element being electricallyconnected with a pair of conductivebands 66 which surround said base adjacent to its opposite ends, said bands being prefer-.

ably inset from the ends of the base as shown. In practice, the resistance element is surrounded by a cementitious covering extending between the bands'7.

Each 01: the bands 6 is bentto provide a pair of downwardly projecting lugs 8' 1 Letters Patent.

provided. with a cl tions serve as feet to within the flanges of Patented Feb. 4, 1919. Serial No. 9935;.

which terminate in parallel overlapping por tions 9 spaced 'from the periphery of the base 5. Each pair of amplng screw 10 for drawing the same together clamping the band firmly about the base 5. 'eparallel overlapping parts 9 of each band '6 are. clamped together and in rigid engagement with a tive strip 11 by rivets 12 passing through the aforementioned is attached to opposite ends of each unit. Each conductive strip 11 is provided with a downwardly bent portion 13 which por support the resistance units and are at their outer ends clamped upon binding posts 14: which extend upward through the flat base 2 thus providing suitable line connections for the various gaged.

The casing 3 comprises a pair of flanged 16 and a single perfointegral end pieces rate front and side piece 17 shaped to fit about the requisite piece 17 also has its ends extended to the base 2 and there inbent as shown in Fig. 3, while bolts 18 are passed through the and thereby relatively heavy conduc- I parts, whereby a strip 11 i i connections are established through the unit terminals not otherwise ennumber of units 1 and the end pieces.l6.' The- 86 I bores of the resistanceunits' 1 and through registering openings in the end pieces 16 of the casing, whereby the casing is supported byand .firmly clamped upon the units. On the other hand, the casing being thus attached to the units serves toreinforce and rigidifythe latter.

at I claim as new and desire to secure by Letters Patent is:v

1. In a resistance device, the combination with a flat insulating base, of a resistance unit comprising an elongated insulating core and a resistanceelement surroundingthe same, andcombined termlnal and supends of said unit art clamped about said y connected. to said reporting devices on opposite each including a core and eleotrica sistance element and a projecting part arranged at substantially right angles to said unit comprising an elongated insulating core and a resistance element surrounding the same, combined terminal and supporting devices on opposite ends of said unit each including a part clamped about said core and electrically connected to said resistance element and a part arranged at substantially right angles to said former part and projecting beyondthe end of said core and binding posts associated with the latter part of said devices serving to anchor the same to the face of said base.

3. A; resistance unit comprising a base, a resistance clement surrounding said base, conductive bands surrounding said base near its opposite ends but inset therefrom, said bands being in electrical engagement with said resistanceelement and each being provided with downwardly projecting lugs and overlapping sections spaced from said base, conductive strips riveted at their inner ends to the overlapping sections of said bands and having their outer ends bent to constitute supporting means for said unit, and binding posts associated with said outer ends of said strips, said binding postsconstituting anchoring means for said unit.

4. In a resistance device, the combination with a flat insulating base, ofa plurality of resistance units having individual terminal devices, said devices being secured to the face of said base to support their respective units, an inclosing casing for saidunits and secure said casing thereto.

5. In a resistance device, in combination, a plurality of resistance units having individual conducting and supporting means, an inclosing casing for said units and means for supporting the same comprising bolts passing axially through each said unit and 1 through alined openings in said casing.

6. In a resistance ,device, the combination with a resistance unit comprising a cylin drical insulating base having a longitudinal bore, a resistance elenientsurrounding said base, conductive clamping bands also surrounding said base and in contact with said resistance element, of a casing extending about said unit and secured thereto by a vbolt passing through said bore, and supporting means for said unit and said caslng ineluding fixed conductive strips rigidly and electrically connected to said'bands.

7. In a. resistance device, the combination with a plurality of resistance units each including a base, a resistance element and conductive clamping bands surrounding said base and contacting with said element, of a casing extending about said units and secured. to certain of the same, and fixed conductive strips rigidly and electrically connected to said bands for supporting said units and said casing and providing electrical connections for the former.

In witness whereof, have hereunto snbscribed my name.

ALBERT J. HORTON.
